1.1 This peicaion covers grades of nominal wall thick-ness, stainless steel tubing for services requiring general corrosion resisiance, with particular emphasis on resistance 1o stress corrosion cncking. These steels are susceptible to embritlement if used for prolonged peniods a elevated tem-peratures.
1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standarnd. The values satedl in each system may not be cxaCt equivalents; therefone, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. Within the text, the SI units are shown in brackets. The inch-pound units shall apply unless the M designation of this specification is specinied in the order.
